Product Details

Part number 20333 is part of Gates’ molded coolant hose program, a broad replacement line for radiator and heater hose service. This hose is shaped for specific coolant paths rather than universal trimming, which helps simplify replacement on vehicles that require a formed hose. It is listed for pipe-to-water-inlet use on 2012-2017 Toyota Camry and 2013-2018 Toyota Avalon, along with additional Toyota and classic vehicle applications. Gates 20333 is also referenced for Toyota Sienna cooling system service, making it a practical choice when replacing a worn or leaking molded hose.

This part cross-references Dayco 70195 and 70239 for the same application.

Common Problems This Hose Can Address

• Coolant leaks from cracked or aged molded hose material
• Softening, swelling, or collapse in the original radiator hose
• Improper hose routing after prior repair or replacement
• Loss of coolant flow at the pipe-to-water-inlet connection
• Service issues on Toyota Camry, Toyota Avalon, and Toyota Sienna cooling systems

Installation Notes and Tips

Verify the hose shape, end diameters, and centerline length against the removed part before installation. Confirm the vehicle’s exact engine and cooling layout, especially on applications noted with pipe-to-water-inlet routing or special hose requirements. Inspect clamps, mating tubes, and nearby coolant components for wear before installing the new hose.
